6. German Shepherd
The German Shepherd is one of the top working breeds, often used for army and police work. Obedient and loyal, they are full of energy and are also known for excelling at canine sports such as agility and flyball. Highly adaptable and suited to just about any job, they have even been used as doggy grooms on farms and ranches, helping to herd horses back into stables after a hack out.
